Abstract: A method for mitigating interference at a small base station in a hierarchical cell structure is provided. In the method, the small base station checks a sub-frame allocated to macro user equipment by using a downlink signal received from a macro base station when an interference candidate user equipment list is received. The interference candidate user equipment list contains information on the macro user equipment adjacent to a femto cell controlled by the small base station. Then the small base station allocates other sub-frame to femto user equipment located in the femto cell by avoiding the sub-frame allocated to the macro user equipment.

Abstract translation: 提供了一种用于减轻分层小区结构中的小型基站的干扰的方法。 在该方法中，当接收到干扰候选用户设备列表时，小型基站通过使用从宏基站接收的下行链路信号来检查分配给宏用户设备的子帧。 干扰候选用户设备列表包含与由小型基站控制的毫微微小区相邻的宏用户设备的信息。 然后，小基站通过避免分配给宏用户设备的子帧来将其他子帧分配给位于毫微微小区中的毫微微用户设备。
